What is the difference between having a Bluetooth connection versus a Wi-Fi connection?

A Wi-Fi connection provides access to Amazon’s platform via the internet, which includes Alexa
voice assistant. It allows you to control music/content service from Amazon Prime Music,
iHeartRadio, TuneIn Radio, and more through verbal commands.

Bluetooth allows you to stream other music/content services directly from your phone to the
speaker via the services’ app.
